Abstract

PURPOSE:To achieve the correction of time with a bette operability and a simple construction by manually rotating a permanent magnet rotor of an electromechanical converter to correct time while the corrected time is indicated by an induced voltage of a stator coil. CONSTITUTION:A crown 9 as external operation member is rotated, a wheel train 7 turns to correct time with a driven pointer 8. In response to the turning of the wheel train 7, a permanent magnetic rotor of a step-motor 6 for an electromechanical converter rotates and the corrected value of time is indicated on a display section 14 by an induced voltage of a stator of a motor 6 according to the level of rotation thereof. Such a simple constructin using the crown eliminates the operation of complicated push switches thereby enabling the correction of time with a better operability.
